Class MultiThreadedJLanguageTool

java.lang.Object

org.languagetool.JLanguageTool

org.languagetool.MultiThreadedJLanguageTool

public class MultiThreadedJLanguageTool
extends JLanguageTool

A variant of JLanguageTool that uses several threads for rule matching. Use this if you want text checking to be fast and do not care about the high load that this might cause. Call shutdown() when you don't need the object anymore.

Also see the javadoc of JLanguageTool.

Thread-safety: this class is not thread-safe, see the remarks at JLanguageTool.
